HTML

<view class="form-item-input" v-if="item.type=='text'">
	<input name="input" 
            autocomplete="on" 
            :placeholder="item.des ? item.des:'请输入'"
			v-model="item.value" 
            @focus="showHistory(item)"
			@input="findHistory"  
    />
	<!--历史记录!-->
<view  v-if="selectFilter.widgetName == item.widgetName" class="history" style="width: 100%;position: absolute;background: #FFF;border: 2rpx solid #ccc; z-index: 999;border-top: none;">
	<view 
		v-for="(history,index) in searchList"
		:key="index"
		v-if="item.widgetName == history.widgetName"
		@tap="historySearch(history)"

	>								
		{
   
   { history.value }}								
	</view>
</view>
